More sleep could prevent many seniors' injuries

A new study in the Archives of Internal Medicine finds poor sleep makes women 70 or older more likely to fall down.

The risk is there even after taking into account things such as weight, age and the use of sleep medications, according to researchers.

Women in the study who slept no more than 5 hours per night had a 50 percent higher risk of having two or more falls over the course of a year than those who slept more than seven hours.

Researchers say the study was done only in women but it's believed the same can be said for elderly men.
